The answer to your question is: .75 = 3x - .03
How to solve it:
x = the cost of a pack of gum twenty years ago
.75 = 3x - .03
+ .03 + .03
.78 = 3x
/ 3 / 3
.26 = x
If a pack of gum now costs 75 cents, which is 3 cents less than three times what a pack would have cost 20 years ago, then a pack of gum would have cost 26 cents.

all students on the track-and-field team

if the coach wants to find out if they prefer track or field he/she has to ask the people who are experiencing it right now and tell him or her if they prefer this or not
Lets begin with our y=mx+b, our constant(b) is 800 that she earns as a salary, our x represents the amount she sells, m then represents the commission which is 8.25% so converting that to a decimal and replacing it as m gets us y = 0.0825x+800. Replace $4500 for x and we have y=0.0825(4500)+800 solve and we get $1171.25
